 wherein the coffee bean storage bunker, the grinder burr assembly and the powder scraper are fixed to the rotating shaft in turn and toward a direction away from the first motor; 
 wherein the powder scraper is fixed to an end of the rotating shaft; and wherein the powder scraper is inside the coffee powder collector. 
 
     
     
       2. The automatic coffee grinding capsule making machine of  claim 1 , wherein the grinder burr assembly comprises a burr bracket, a first burr, and a second burr, wherein the burr bracket is vertically fixed to the rotating shaft, and wherein the first burr and the second burr can each be dismantled from and fixed to the burr bracket. 
     
     
       3. The automatic coffee grinding capsule making machine of  claim 2 , wherein the grinder burr assembly comprises a grinder burr interval regulator, and wherein the grinder burr interval regulator is used for regulating a distance between the first burr and the second burr and regulating a fineness of ground coffee. 
     
     
       4. The automatic coffee grinding capsule making machine of  claim 3 , wherein there is a first spring at a lower part of the coffee bean storage bunker, wherein the first spring is mounted around the rotating shaft, and wherein one end of the first spring is connected to the coffee bean storage bunker, and another end of the first spring is connected to the grinder burr assembly. 
     
     
       5. The automatic coffee grinding capsule making machine of  claim 1 , wherein the coffee powder temporary storage device comprises a second motor, a second detecting device, and a movable mechanical part; wherein the second motor is used for driving movement of the movable mechanical part; wherein the second detecting device is used for detecting whether the movable mechanical part is in place or not; wherein inside the movable mechanical part, there is a volume-changeable cylinder cavity; wherein the cylinder cavity is used for placing coffee powder conveyed from the coffee powder collector; and wherein when the cylinder cavity is filled with coffee powder, the second motor drives the movable mechanical part to move. 
     
     
       6. The automatic coffee grinding capsule making machine of  claim 5 , wherein the powder tamping and removal device comprises a third motor, a third detecting device, a second spring, a powder tamper, a flat scraper, and a waste storage bin; wherein the third motor is connected to the powder tamper, and the second spring is mounted around the powder tamper; wherein the third motor is used for driving the powder tamper to move upward or downward; wherein the third detecting device is used for detecting whether the powder tamper is in place or not; wherein the second spring is used for buffering a pressure exerted by the third motor on the powder tamper; wherein the flat scraper is used for removing redundant coffee powder outside the coffee cup; and wherein the waste storage bin is used for storing discarded coffee powder. 
     
     
       7. The automatic coffee grinding capsule making machine of  claim 6 , wherein the coffee cap unloading device comprises a fourth motor, a fourth detecting device, a push rod, a coffee cap tray, and a sliding track; wherein the fourth motor drives the push rod and causes a coffee cap to move along the sliding track and cap the coffee cup; and wherein the fourth detecting device is used for detecting whether there is a coffee cap on the coffee cap tray or not. 
     
     
       8. The automatic coffee grinding capsule making machine of  claim 7 , wherein the capping device comprises a drum, a roller, a third spring and a connection device; and wherein the roller is provided at both ends of the drum, and the roller is connected to the connection device via the third spring. 
     
     
       9. The automatic coffee grinding capsule making machine of  claim 8 , wherein the drum comprises a first drum and a second drum; wherein the first drum covers an outside of the second drum; wherein the first drum is made of soft rubber; wherein the second drum is made of hard rubber; and wherein when the coffee cap caps the coffee cup, the capping device presses the coffee cap.
